Phacus
From the collection
Protsville drawings of freshwater protists
| Description of Phacus: Euglenid, with plastids, rigid, flattened cells, most species very flat and leaf-shaped, often with ridges, folds or grooves running helically or longitudinally, giving an irregular or triradiate cross-section; many species with a long posterior spine, many twisted, flagella, eyespot and flagellar swelling as in Euglena; chloroplasts usually small, discoid, numerous, without pyrenoids; a few species (e.g. P. splendens) have large flat chloroplasts with pyrenoids; paramylon is typically deposited as a few large granules (often rings) together with many small ones; canal opening subapical; no cysts palmelloid stages rare; speciose, contemporary studies indicate that the genus is not monophyletic or holophyletic; type species: P. longicauda (Ehrenberg, 1833) Dujardin, 1841. |
